No bug. That has always been that way.
Flap damage is modled so as the flap "damaged" is stuck in the position it was in when it "fell off." So, you were hit, obviously, with 10% flaps deployed because the tip stall to the right goes away when you put the good flap out.

Makes sense to me sir but i guess i am just saying that i have never had that experience before.
I guess that every time i have had a flapp shot off it was in the fixed up position.
I still made it home though landing five kills and not to my flying credit so much, I'M pretty sure i was just lucky.
thanks for the 411 on this matter.
